Abstract

In this paper, the method of DOFs condensation is adopted to simulate hinge node in finite element analysis. Other than adding additional overlapped nodes for the DOFs coupling method, the principle idea of DOFs condensation method is that each two elements connected by a hinge node do have a common node, which is exactly the hinge node, while the non-constrained DOFs of the hinge node would be condensed into the other constrained DOFs of the element. The procedure of condensation is much like the condensation of sub-structures. The detailed condensed stiffness matrices for beam elements is derived in this paper. A numerical example for a hinged frame is presented. The validity of the present theory would be demonstrated by comparing the present result and that of ABAQUS software.
